图1所示是我厂加工的零件,由于形位公差的要求需一次装夹加工完,其中锥度角5°±2′无法在加工中精确测量,我们自制了如图2所示量具。使该锥度角得到了精确测量。
Figure 1 shows the parts machined by our factory. Due to the requirement of shape and position tolerance, a clamping process is required. The taper angle of 5 ° ± 2 ’can not be accurately measured in the process. We made the gauge as shown in Fig.2. The taper angle is precisely measured.
